   1 1/4  cups          salad oil or olive oil or a mixture of
                        -- the two
     3/4  cup           soy sauce
   2 1/4  teaspoons     salt
     1/2  cup           red wine vinegar
   1      teaspoon      crushed garlic -- or more to taste
     3/4  cup           Worcestershire sauce
   2      tablespoons   dry mustard

                        -- best
   1      teaspoon      dried parsley flakes
     1/3  cup           lemon juice

Preparation:

In a one quart jar, combine the above ingredients. Prepare this marinate at least 6 hours in advance of use and always marinate meat for 6 -8 hours or overnight. Baste during the grilling/smoking process. Mop it on before serving. This is a marinate, basting, and serving sauce for the smoker or the grill. For chicken, beef or chops. I have been using this recipe for many years and I particularly like it on London Broil (cut 2 to 2 1/2" thick, grilled to very rare) or grilled/ smoked chickens.
